In epidemiological studies, it is easier to glean information from isolated populations with simple genetic backgrounds than from populations with relatively complex genetic backgrounds. Regarded as an isolated population, the Minz (Hei-Yi Zhuang) in Napo County (in the China-Vietnam borderland) has been the subject of numerous recent studies. To assess the genetic isolation of this population, we studied Y chromosome and mitochondrial DNA from Minz and Han in Napo.

- The Han Chinese, the largest ethnic group globally, consists of various branches, among which the Pinghua branch has been less studied but is believed to derive from ancient southern minorities.
- Genetic analyses of 470 samples show that Pinghua populations display high frequencies of certain Y chromosome haplogroups and mtDNA lineages similar to those found in nearby indigenous groups, indicating a closer relationship with southern minorities than with other Han branches.
- Overall, the findings suggest that while the Pinghua have adopted Han Chinese culture and language, their genetic roots trace back to southern minorities rather than the broader Han Chinese lineage.
